| Following structures are haploid, diploid or triploid: | |
| A-Oosphere | B-Microspore |
| C-Synergids | D-Antipodal cell |
| E-Oospore | F-Nucellus |
| G-Endosperm | H-Tapetum |
| Which of the following groups show the correct sequence of ascending order of ploidy in ovule/seeds? | |
A) C B D
B) A E G
C) E F H
D) C D G
Correct Answer: B
Solution :
| The structures found in ovule/seed and their ploidy levels are as follows: |
| A - Oosphere (n) |
| C - Synergids (n) |
| D - Antipodal cell (n) |
| E-Oospore (2n) |
| F-Nucellus (2n) |
| G-Endosperm (3n) |
| As per options, option [b] with structures Oosphere [A], oospore [E] and endosperm |
| (G) Show the correct sequence of ascending order of ploidy in ovule/seed. Tapetum (H) is innermost layer of anther wall and its ploidy level is 2n. |
